The U.S. government will allow oil and gas companies to make lease bids Monday on lands considered archaeologically sensitive near a national monument stretching across the Utah-Colorado border that houses sacred tribal sites. Included in the Bureau of Land Management’s September oil and gas lease sale is about 47 square miles (122 square kilometers) of land north of Hovenweep National Monument, a group of prehistoric villages overlooking a canyon with connections to several indigenous tribes throughout the U.S. Southwest.
